없음 Traditional landfill capping methods, which involve a final cover layer, can extend the post-closure care period for severaldecades, shifting the environmental and economic impacts of landfills to future generations. To promote more sustainable landfillsand mitigate the burden on future generations, it is essential to shorten the post-closure care period and reduce methane emissionsby employing low-pressure aeration landfill methods. The implementation of low-pressure aeration requires careful consideration ofvarious factors. These include the method of air injection, layout of injection wells, appropriate amount and pressure of air injection,and the control of temperature and moisture content. Additionally, it is essential to consider the emission characteristics of methaneand nitrous oxide, establish comprehensive monitoring plans, and set definitive criteria for the completion of landfill aeration. Thisstudy reviews the behavior of gaseous carbon and nitrogen and examines the operational considerations crucial for effectivelyimplementing the low-pressure aeration landfill method.

PCM의 기본단말인 신형 D-4 channel bank의 개발에 있어서 alarm과 trunk pocessing unit에 마이크로프로세서를 활용하여 많은 기능을 부가하였고 이로 인해 회로소자의 간소화와 높은 신뢰성을 얻게 되었다. LSI기술을 지향하는 선진국에 반하여, 아직 국내 반도체산업의 후진을 면치 못하는 우리 나라의 경우 산업용 시스템에 마이크로프로세서의 응용은 경제성, 신뢰성, 기술성에서 높은 의의를 준다. In the recent developent of D-4 Channel Bank which is the basic PCM multiplex terminal, we utilized the one-chip microprocessor in the design of the Alarm and Trunk processing unit besides we could add more flexible functions, we simplified the logic circuits and the discrete parts. Since in Korea, we are lacking in the semiconductor technology, the microprocessor applications in the communication systems desist give us the meaningful advantages in the a aspects of economy, reliability and new technology.
